Check Digit Verification of cas no

The CAS Registry Mumber 57693-96-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,9 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57693-96:
(7*5)+(6*7)+(5*6)+(4*9)+(3*3)+(2*9)+(1*6)=176
176 % 10 = 6
So 57693-96-6 is a valid CAS Registry Number.

Dichotomy of Manganese Catalysis via Organometallic or Radical Mechanism: Stereodivergent Hydrosilylation of Alkynes

Yang, Xiaoxu,Wang, Congyang

supporting information, p. 923 - 928 (2018/01/01)

Herein, we disclose the first manganese-catalyzed hydrosilylation of alkynes featuring diverse selectivities. The highly selective formation of E-products was achieved by using mononuclear MnBr(CO)5 with the arsenic ligand, AsPh3. Whereas using the dinuclear catalyst Mn2(CO)10 and LPO (dilauroyl peroxide) enabled the reversed generation of Z-products in good to excellent stereo- and regioselectivity. Such a way of controlling the reaction stereoselectivity is unprecedented. Mechanistic experiments revealed the dichotomy of manganese catalysis via organometallic and radical pathways operating in the E- and Z-selective routes, respectively.

Synthesis and structural studies of phosphorus carbonyl manganacycles containing the tetraphenyldiselenoimidodiphosphinato ligand

, p. 3223 - 3231 (2007/10/03)

The [Mn(CO)4-x(L){Ph2P(Se)NP(Se)Ph2-κ 2Se}] complexes, where x = 1 for L = PPh3 and PMePh2, and x = 2 for L = Ph2PCH2CH2PPh2 (diphos), were synth

Photochemical reactions between dinuclear metal carbonyl complexes and alkyl halides. Formal oxidative addition across a metal-metal single bond proceeding by a free radical chain mechanism

Biddulph, Michael A.,Davis, Reg,Wilson, Fiona I. C.

, p. 277 - 293 (2007/10/02)

Photochemical reactions between (L = CO, PBu3, PEt3, P(OMe)3, P(OPh)3, PPh3) and alkyl halides (RX) yield both alkyl and halo complexes, and , in equimolar quantities.Kinetic and quantum yield studies suggest that these reactions proceed by a radical chain pathway involving CO dissociation from the dinuclear complex and metal-metal bond homolysis of the coordinatively unsaturated dinuclear intermediate.

Engelbrecht, Juergen,Greiser, Thomas,Weiss, Erwin

, p. 79 - 92 (2007/10/02)

Several oxoalkylpentacarbonylmanganese compounds RC(O)CH2Mn(CO)5 (R = Me, Ph, MeO) have been synthesized and investigated (IR, 1H NMR, mass spectra).They are thermo- and photo-labile and can be stabilized by triphenylphosphine substitution.Thus acetonylte
